When discussing the safety and durability of steel structure buildings, the selection of fire retardant coating is particularly important. Great Wall Group is a professional fire retardant coating supplier, we know that different brands, models of steel structure fire retardant coating in the physical and chemical performance of significant differences. Today, we will start from several key dimensions to compare the physical and chemical properties of mainstream steel structure fire retardant coatings for you.
1. Fire resistance time
Fire resistance time is the primary index to measure the performance of fire retardant coatings. We recommend GT-NSP-Fp2.50-1C-HG expansion steel structure fire retardant coating, under the standard test conditions, can reach the fire resistance limit of more than 2 hours, far beyond the industry standard, providing a more reliable fire barrier for steel structure buildings. In contrast, some similar products on the market, their fire resistance time is only about 1.5 hours, which can meet the basic needs, but may be slightly insufficient under extreme fire conditions.
2. Coating thickness and adhesion
The coating thickness directly affects the thermal insulation effect and service life of the fireproof coating. GT-NSP-Fp2.50-1C-HG Expansion steel structure fire retardant coating in ensuring good fire resistance, but also has excellent coating adhesion, even in the complex and changeable construction environment, but also to ensure the close combination of the coating and the surface of the steel structure, effectively prevent the coating from falling off. While other similar fire-retardant coatings, although the coating thickness is moderate, but in certain specific conditions, its adhesion performance is slightly inferior.
3. Weather resistance and corrosion resistance
Steel structure buildings are exposed to the natural environment all the year round, so the weather resistance and corrosion resistance of fire-proof coatings are equally important. GT-NSP-Fp2.50-1C-HG Expansion steel structure fire retardant coating adopts advanced formula, can resist ultraviolet light, wind and rain erosion and corrosion of chemical substances, to ensure that the coating maintains stable fire performance for a long time. Other similar fire retardant coatings also have good performance in weather resistance, but in a specific corrosive environment, its durability may be affected.

4. Environmental protection performance
With the enhancement of environmental awareness, the environmental performance of fire retardant coating is also increasingly concerned. GT-NSP-Fp2.50-1C-HG Expansion steel structure fire retardant coating in the production and use process, are in line with the national environmental protection standards, low VOC (volatile organic compounds) emissions, harmless to human health and the environment. We know that the choice of environmental protection fire retardant paint, is not only responsible for customers, but also responsible for the society.
5. Convenience of the construction
The convenience of construction is also one of the factors that customers need to consider when choosing fireproof coatings. GT-NSP-Fp2.50-1C-HG Expansion steel structure fire retardant coating has good construction performance, whether it is spraying, brushing or roller coating, can easily achieve uniform coating, reduce the construction difficulty and time cost. At the same time, its fast drying speed is conducive to shorten the construction period and improve the engineering efficiency.
To sum up, the Great Wall GT-NSP-Fp2.50-1C-HG expansion steel structure fire retardant coating in fire resistance time, coating thickness and adhesion, weather resistance and corrosion resistance, environmental performance and construction convenience, is your ideal choice to protect the safety of steel structure building and improve the building quality. We look forward to working with you to contribute to the safety and sustainable development of steel structure buildings.
